查找并返回另一个单元格值，其间有单元格间隙

Question

我基本上被困在这个 VBA 中，因为我不知道如何查找 2 个单元格并返回另一个单元格值。可能是先读取项目名称进行查找，然后读取周数以匹配并返回灰色区域中的阶段，但是将两个查找放在一起对我来说很困难。

This is the first sheet where the input come in as week number and date in each phase

The second sheet will search the project number and week number, return the phase in column J and next.

Answer 1

使用几个Dictionary Objects 作为项目行和周列的查找。

Option Explicit

Sub Macro()

    Const SHT_PRJ = "Project"
    Const COL_ID_PRJ = "E"
    Const COL_PH1 = "F" ' Phase 1

    Const SHT_DEM = "Demand"
    Const COL_ID_DEM = "D"
    Const ROW_HDR_DEM = 1
    Const MAX_PH = 6 ' phases 1 to 6
